The main body structure comprises a roof mounting structure 101 and a display screen mounting bracket 103. The roof mounting structure 101 can be a plate structure or a seat structure, a connecting foot structure, mounted on the roof structure of the vehicle, or a lockable movable structure, such as a lifting structure, a forward and backward sliding structure, or a left and right sliding structure, or a left and right rotating structure.

[0021] The display screen mounting bracket 103 is rotationally connected to the roof mounting structure 101 by a hinge, which can be opened downward and folded upward, and the hinge can adopt a conventional hinge, including a display screen mounting bracket rotating shaft 105. The display screen mounting bracket 103 can be opened downward and folded upward manually or electrically, and can also be driven by a spring mechanism when folded or opened. In the embodiment, the vehicle roof suction telescopic display device is provided with an electric drive device to electrically drive the display screen mounting bracket to fold and / or open. The electric drive device is provided with a motor 104 mounted on the roof mounting structure 101, and the motor 104 is connected to the driven display screen mounting bracket rotating shaft 105.

[0022] The display screen mounting bracket 103 is a telescopic mounting bracket and is provided as a flexible screen folding mechanism. The display screen mounting bracket 103 can be composed of two parts, a rotating connecting bracket 1031 and a sliding bracket 1032. The rotating connecting bracket 1031 is rotationally connected to the roof mounting structure 101 by the above structure, and the sliding bracket 1032 is slidingly connected to the rotating connecting bracket 1031 in the telescopic direction. The sliding connection can be achieved by guide rails, and can be manually or electrically driven. When electrically driven, a screw nut 1034 and a sliding bracket 1032 can be connected between the rotating connecting bracket 1031 and the sliding bracket 1032, and a screw rod 1033 is connected to a motor 1035, and the motor 1035 is mounted on the rotating connecting bracket 1031, or a belt drive mechanism can also be used to drive the telescopic movement.

[0023] The flexible screen 102 is connected to the folding mechanism and can change the display screen flat area and finely adjust the display screen height with the display screen mounting bracket telescoping to support the flat flexible screen.

[0024] The flexible screen 102 has one end as a movable end and the other end as a fixed end. The fixed end is mounted to one of the rotating connecting frame 1031 and the sliding frame 1032, and the movable end is mounted to the other of the rotating connecting frame 1031 and the sliding frame 1032. In this embodiment, the flexible screen is stretched and retracted in the up-down direction (i.e. the height direction) of the display screen, and the movable end is preferably connected to the rotating connecting frame 1031. Specifically, a sliding mounting plate 108 can be arranged on the rotating connecting frame 1031, and the movable end is connected to the sliding mounting plate 108. The fixed end of the flexible screen is fixedly connected to the sliding frame. The movement of the sliding mounting plate 108 can also be driven by the motor 1035. A driving connection structure composed of a synchronous gear mechanism 1036, a screw rod 1037 and a nut 1038 can be arranged. The nut 1038 is connected to the sliding mounting plate 108, the screw rod 1037 is connected to the nut 1038, the end of the screw rod 1037 is connected to the synchronous gear mechanism 1036, and the synchronous gear mechanism is connected to the output end of the motor 1035.

[0025] The flexible screen connection structure of the fixed end can be a fixed plate surface or a clamping structure on the sliding frame 1032 that can be fixed (such as bonded) with the flexible screen. In addition, a flexible screen guide shaft 107 is arranged at the end of the rotating connecting frame 1031 for the flexible screen to pass around. A flexible screen support structure can also be arranged in the display screen mounting frame. The flexible screen support structure can be a plate, or composed of multiple strips or multiple pieces, or composed of a mixture of the above-mentioned components.

[0026] In this embodiment, the flexible screen is vertically retracted and extended, i.e. the retraction and extension direction is the up-down direction. Therefore, when the display screen mounting frame 103 is in the folded state and is retracted to the smallest size, its size in the longitudinal direction of the vehicle can be only half or even smaller than the size of a normal display screen, and the flexible screen can be adjusted by retraction and extension, so that the length-width ratio of the screen can be accurately adjusted for different display formats.

The roof mounting structure 201 can be a plate structure or a seat structure, a connecting foot structure, or a lockable movable structure mounted on the roof structure of the vehicle, such as a lifting structure, a forward and backward sliding structure, a left and right sliding structure, or a left and right rotating structure.

[0029] The display screen mounting rack 203 is a telescopic mounting rack, which is a transverse telescopic mounting rack, and the flexible screen 202 is also transversely retracted and extended. The display screen mounting rack 303 is a telescopic mounting rack arranged on both sides of the display screen mounting rack 203 in the transverse direction and is arranged as a retraction and extension mechanism of the flexible screen.

[0030] The retraction and extension mechanisms on both sides are symmetrical. The display screen mounting rack 203 includes a middle rotating connection rack 203A and left and right sliding racks 203B and 203C arranged on both sides of the middle rotating connection rack 203A and slidingly connected with the middle rotating connection rack 203A in the transverse direction. A turning guide shaft 206 is arranged at the end of the sliding racks 203B and 203C, so that the flexible screen is bent into two layers in the display screen mounting rack 203, and the height of the display screen can be finely adjusted, the display screen area and the aspect ratio can be changed, and the display screen can be retracted and extended.

[0031] The sliding connection structure of the left and right sliding racks 203B and 203C and the middle rotating connection rack 203A in the telescopic direction can be realized in a guide rail mode. The middle rotating connection rack 203A is rotationally connected with the roof mounting structure 201. The sliding can be manually or electrically driven. When electrically driven, the structure of embodiment 1 can be used.

[0032] The display screen mounting rack 203 (the middle rotating connection rack 203A and / or the left and right sliding racks 203B and 203C) can be provided with a support structure of the flexible screen, which can be a plate or composed of multiple strips or multiple pieces or a mixture of the above-mentioned components. The connection between the flexible screen 202 and the middle rotating connection rack 203A, the left and right sliding racks 203B and 203C can be bonding, clamping, etc.

[0033] The middle rotating connection rack 203A in the display screen mounting rack 203 is rotationally connected with the roof mounting structure 201. The display screen mounting rack 203 can be manually or electrically folded down and unfolded up. When folded or unfolded, an elastic mechanism can be used for driving. In this embodiment, the vehicle-mounted ceiling telescopic display device is provided with an electric driving device, which can electrically drive the display screen mounting rack to be folded and / or unfolded. The electric driving device is provided with a motor, and the motor is connected with the rotating shaft of the driven display screen mounting rack.

[0034] The display screen of the embodiment is narrow in width when being folded, and can be expanded in width during use, and can provide large size for left and right split screen display, and can consider left and right passengers, and can reduce the distance with left and right passengers, and can help to reduce the size in the height direction.
